基于质点振荡的模型和数值模拟的方法，研究了波导参数和传播常数对光折变晶体与线性电介质界面光折变表面波类型和局域表面波模的影响。当波导参数大于传播常数时，在光折变晶体与线性电介质界面可以产生非局域表面波。当波导参数小于传播常数时，在光折变晶体与线性电介质界面可以产生振荡表面波和局域表面波。在局域表面波形成的系统内，正波导参数的光波能量比负波导参数的光波能量在光折变晶体内聚集得多。在给定一个局域表面波形成的物理系统，传播常数越大，表面波在线性电介质和光折变晶体中衰减就越快，对应表面波模的波峰离界面就越近。

In terms of the particle oscillator model and numerical techniques, the influences of guiding parameters and propagation constants on surface wave types and localized surface modes at the interface between the photorefractive crystal and the linear dielectric medium are studied. When the guiding parameter is greater than the propagation constant, delocalized surface waves can occur at the interface between photorefractive crystal and linear dielectric medium. When the guiding parameter is less than the propagation constant, shock surface waves and localized surface waves can occur at the interface between photorefractive crystal and linear dielectric medium. In localized surface wave systems, the wave energy in the photorefractive crystal for the positive guiding parameter is more collective than the one for the negative guiding parameter. For a given physical system of the localized surface wave, the higher the propagation constant, the faster the surface wave attenuation in the linear dielectric medium and the photorefractive crystal, and the closer the crest factor of corresponding surface mode toward the boundary.
